Answer:
The formula is: Magnification = Image Size ÷ Actual Size
We know the actual size of the object is 5 cm. The magnification is 10x × 20x = 200x.
Therefore, 200x = Image Size ÷ 5 cm
Image Size = 200x × 5 cm = 1000 cm
Since 1000 cm = 10 m, the student needs to draw the circle at a scale of 1:10. This means that 1 cm on the drawing represents 10 cm in reality.
The scale at which the student needs to draw the circle is 1:10.
